Runs

Each hourly and 6-hourly init we finished in the last 24 hours

Surface maps use the newest hourly run for hours 1 through 48, then the latest 00, 06, 12, or 18Z run every 6 hours out to 15 days. Upper-air maps are the 64-member mean from that same 6-hourly run only. This board updates when a cook finishes.
